| |
LM | cystic lesion with ciliated epithelium surrounded by fibrous stroma, psammoma bodies |

Clinical history | may be associated with endometriosis; incidental finding |
Prognosis | benign |
General
- Benign entity that may lead to a misdiagnosis of adenocarcinoma[1] or serous carcinoma.
- The clinical significance of endosalpingiosis is not definitively settled; opinions differ on whether it is:
Microscopic
Features:[4]
- Cystic lesions with:
- Ciliated (tubal type) epithelium, without endometrial stroma.
- Endosalpingiosis is surrounded by fibrous stroma; tubal type epithelial surrounded by ovarian stroma is a variant of endometriosis.
- Ciliated (tubal type) epithelium, without endometrial stroma.
- Associated with psammoma bodies.[5]
Notes:
- Not associated with hemorrhage.[6]
- In a lymph node, endosalpingiosis may be misinterpreted as a metastasis![7]
DDx:[8]
- Serous carcinoma.
- Peritoneal inclusion cyst.
- Adenocarcinoma.
- Papillary carcinoma.
